SUMMARY: Silver fir (Abies albaMill.) is naturally distributed in mountainous regions of central, southern and parts of western Europe (Figure 1). Ecologically, commercially and traditionally, silver fir is the most important Croatian conifer species, participating in the total conifer growing stock with about 35 % (Prpić and Seletković 2001). It occurs in selection forests, which represent an important ecological stronghold of the most forested region in the Republic of Croatia. The stand’s health status is assessed by monitoring the crown condition of individual trees. Dobbertin and Brang (2001) showed that mortality rates increase exponentially with increasing defoliation. Crown damage can be monitored indirectly and directly, but neither of these methods is completely objective (Redfern and Boswell 2004). The health status of forests in Europe is monitored on an annual level within the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests, ICP FORESTS. The programme was launched in 1985, and the Republic of Croatia joined in 1992. Monitoring is repeated in permanent plots by indirect (visual) assessment of crown defoliation of freely grown trees. |
